How to use Pilz's safety relay PNOZ X2.7PX2.8P In the previous article, we talked about Pilz's safety relay (PNOZ X3). Today we will talk about Pilz's other two safety relay products: PNOZ X2.7P and PNOZ X2.8P.

How does a stepper motor work What are its characteristics？ We will learn the following: 1) What is a stepper motor; 2) Some basic concepts related to stepper motors; 3) Classification and structure of stepper motors; 4) Features of stepping motor;

Understanding stepper drives We know that a stepper motor is composed of a stator and a rotor. The stator winding generates an induced magnetic field after energization. The induced magnetic field interacts with the rotor to make the rotor rotate through a certain angle.

Getting started with SINAMICS V90 servo drive system (2)-STO function Today in this article, we will introduce the STO function of the V90 servo drive.

How to use the diagnostic functions of the Festo bus node CPXFB33 A good bus module not only needs to be able to provide stable and reliable functions, but also needs to be able to quickly and easily inform the cause of the failure when the system fails.

How does an incremental encoder work？ "S7-200 SMARTStepping motor with dynamic control" In the previous two articles, we introduced stepper motors and stepper drives. We know that the stepper motor itself does not have a feedback device. In some occasions that require precise control, it needs to be used with feedback devices such as encoders.

Talking about the signal circuit output mode of incremental encoder We know that encoders can be divided into incremental encoders (Incremental Encoder) and absolute encoders (Absolute Encoder). The main difference between the two is the structure of the encoder and the form of the output signal.

What is the difference between an absolute encoder and an incremental encoder In the previous article, we explained the working principle of the encoder and introduced the incremental encoder in detail. Today in this article we will discuss another type of encoder: absolute encoder.

Field story starting from a tripped miniature circuit breaker One day, the on-site personnel told me that an air switch of the device had tripped. I went to the site and found that the fault was a Siemens miniature circuit breaker connected to the printing device. Miniature circuit breaker, English name

Tips What is the relationship between relative pressure, absolute pressure and vacuum Due to the working relationship, I often deal with fluid/gas pressure. Sometimes I chat with my friends on the spot and find that many of my friends are not very clear about the concept of relative pressure and absolute pressure.
